pub struct PortSlab<T> { /* private fields */ }
Expand description

A data structure that is keyed on Port, guarantees O(1) lookup and takes into account salted port identifiers.

Implementations§

source§

impl<T> PortSlab<T>

source

pub fn new() -> Self

Creates a new empty PortSlab.

source

pub fn insert(&mut self, port: Port, value: T) -> Option<T>

Inserts value indexed by port.

Returns Some(_) if the value is inserted and there was already some value stored in the slab.

source

pub fn remove(&mut self, port: &Port) -> RemoveOutcome<T>

Removes the entry indexed by port, if one exists.

Note that remove will not remove an entry if the currently stored port’s salt doesn’t match port.

source

pub fn get(&self, port: &Port) -> Option<&T>

Gets a reference to the value indexed by port.

get only returns Some if the slab contains an entry for port with a matching salt.

source

pub fn get_mut(&mut self, port: &Port) -> Option<&mut T>

Gets a mutable reference to the value indexed by port.

get_mut only returns Some if the slab contains an entry for port with a matching salt.

source

pub fn entry(&mut self, port: Port) -> Entry<'_, T>

Retrieves an [entry] indexed by port.
